Question

Study the given numbers and justify why each of them cannot be a perfect square 34567

Answer 1

34567 is not a perfect number.

The number supplied to us is 34567.

A number can be a perfect if it ends with the unit digit of the number formed from the square of numbers from 0 to 9.

0² = 0. Eg. 100

1² = 1. Eg. 81

2² = 4. Eg. 64

3² = 9. Eg. 169

4² = 16. Eg. 36

5² = 25. Eg. 625

6² = 36. Eg. 256

7² = 49. Eg. 529

8² = 64. Eg. 144

9² = 81.  Eg. 121

We see that none of the perfect squares obtained have 7 in their units place.

So, 34567 is not a perfect number.
